Ocular drug delivery is one of the most challenging issues in ophthalmology because of the complex physiological structure of the eye. Polysaccharide-based nanomaterials have been extensively investigated in recent years as ideal carriers for enhancing the bioavailability of drugs in the ocular system because of their biocompatibility and drug solubilization. From this perspective, we discuss the structural instability of polysaccharides and its impact on the synthesis process; examine the potential for developing bioactive polysaccharide-based ocular drug nanocarriers; propose four strategies for designing novel drug delivery nanomaterials; and suggest reviewing the behavior of nanomaterials in ocular tissues.

Bilateral Pupillary Involvement as a Clinical Presentation of Herpes Zoster Ophthalmicus

Yan Ma, Yuhe Tian, Xia Chen, Rupesh Agrawal, Yun Feng

Summary: Herpes zoster ophthalmicus (HZO) is traditionally considered as a unilateral disease, but subclinical involvements in the contralateral eye structures are evidence. Our study using a pupillometer and an esthesiometer found significantly abnormal features in both affected and contralateral eyes of HZO patients.

Summary: This case series provides important insights for the management strategy of severe viral keratitis. Evaluation of characteristics of retrocorneal plaques by ASOCT and reduced corneal sensation are valuable aids in diagnosis. Conservative medical management may be a viable option, and IVIG may have a role in speedy resolution of severe cases.

Product spectrum analysis and microbial insights of medium-chain fatty acids production from waste biomass during liquor fermentation process: Effects of substrate concentrations and fermentation modes

Jihua Zhao, Hongzhi Ma, Wenyu Wu, Mohammed Ali Bacar, Qunhui Wang, Ming Gao, Chuanfu Wu, Changlei Xia, Dayi Qian, William Woei Fong Chong, Su Shiung Lam

Summary: Two fermentation modes, electro-fermentation (EF) and traditional fermentation (TF), were used to produce medium-chain fatty acids (MCFAs) from different concentrations of liquor fermentation waste. EF mode at 40% substrate concentration resulted in the highest caproate (4.04 g/L) and butyrate (13.96 g/L) concentrations. TF experiments showed inhibition of ethanol oxidation and products formation above 40% substrate concentration. Compared to TF mode, EF mode significantly increased total substrates consumption by 2.6%-43.5% and product yields by 54.0%-83.0%. EF effectively alleviated substrate toxicity and enriched chain elongation bacteria, promoting ethanol oxidation and products formation. This study offers a new approach for producing MCFAs from high concentration wastewater.

Conversion of liquor brewing wastewater into medium chain fatty acids by microbial electrosynthesis: Effect of cathode potential and CO2 supply

Jihua Zhao, Hongzhi Ma, Wenyu Wu, Mohammed Ali Bacar, Qunhui Wang, Ming Gao, Chuanfu Wu, Changlei Xia, Dayi Qian

Summary: Chinese liquor brewing wastewater (CLBW) can be upgraded to biofuels, specifically medium chain fatty acids (MCFAs), using microbial electrosynthesis (MES). The study found that under-1.0 V/CO2 condition, CLBW had the highest concentration and selectivity of caproate, which was 32.6% and 31.9% higher than the control group. The pH and electrochemical analysis supported the superiority of-1.0 V/CO2 condition. This study provides a new pathway for MCFAs production.

X-Band Radar Attenuation Correction Method Based on LightGBM Algorithm

Qiang Yang, Yan Feng, Li Guan, Wenyu Wu, Sichen Wang, Qiangyu Li

Summary: X-band weather radar provides high-resolution data for precipitation observation and prediction, but it is susceptible to precipitation attenuation. This paper presents and validates an X-band attenuation correction method based on the LightGBM algorithm (the XACL method). The XACL method shows a significant correction effect and reduces the anomalous correction phenomenon compared to other methods. It achieves a 39.88% reduction in average error in precipitation estimation over 1204 meteorological stations.

Summary: Boron deficiency affects sugar beet production, and the use of nutrient-efficient varieties is an important solution. This study aimed to determine the effects of B deficiency on leaf phenotype and photosynthetic functions in B-efficient and B-inefficient sugar beet cultivars. The results showed that B-efficient cultivar had better adaptability to morphological changes and photosynthetic functions under B deficiency, providing theoretical basis for the selection of efficient sugar beet cultivars.

Summary: The development of immune checkpoint blockade therapy has revolutionized cancer therapies, but the heterogeneous expression of PD-L1 in tumor cells hinders its effectiveness. To enhance treatment efficacy, there is a need for better methods to stratify patients and visualize PD-L1 expression. This study designed a new method using a radiolabeled tracer to detect PD-L1 expression in tumors through PET imaging.

Shuo Li, Wenyu Wu, Huaxin Ma, Zhao Zhang, Yu Gu, Jingjie Zhang, Ruijun Zhang

Summary: A newly-developed strategy for preparing layer-tunable graphene has overcome the poor service life issue of graphene oxide (GO)-based membranes in water purification. The assembled graphene membrane with an average layer number of 3 exhibits a high rejection rate of 99.9% for Rhodamine B and a water flux of up to 3452.6 L m-2 h-1 bar-1, thanks to its unique hierarchically nanochannel structure. The membrane also demonstrates superior service performance with the rejection rate of RB maintained at 99.9% even after 24 cycles of filtrations.
